Moves 12 packages from internal/ to pkg/ (config, id, validate, events, db, auth, lifecycle, scheduler, channels, audit, service) so they can be imported by the enterprise repo as a Go module dependency. Introduces pkg/cpextension (shared Extension interface + ServerContext) and pkg/cpserver (Run() entrypoint with functional options) so the enterprise main.go can call cpserver.Run(cpserver.WithExtensions(...)) without duplicating the 20-step server bootstrap. Adds db/migrations/embed.go for go:embed access to OSS SQL migrations from the enterprise module. cmd/control-plane/main.go is reduced to a 10-line wrapper around cpserver.Run.
